DOF Subsea, Sonardyne, 2G Robotics, and Seatronics successfully demonstrated a new underwater surveying technique that could significantly shorten the time needed to map underwater structures and offshore sites.
The new technique uses a 3D laser scanner fitted to an ROV to create highly detailed, point cloud images of subsea assets and environments. By combining the 3D laser data with precise underwater acoustic and inertial navigation information, it is now possible to generate centimetre resolution engineering models from which accurate measurements can be instantaneously and repeatably captured.

http://www.businessinsider.com/animated-map-global-fiber-optic-internet-cables-2015-9 ---- 99% of international data is transmitted by wires at the bottom of the ocean called submarine communications cables. In total, they are hundreds of thousands of miles long and can be as deep as Everest Is tall. The cables are installed by special boats called cable-layers. It’s more than a matter of dropping wires with anvils attached to them—the cables must generally be run across flat surfaces of the ocean floor, and care is taken to avoid coral reefs, sunken ships, fish beds, and other ecological habitats and general obstructions. The diameter of a shallow water cable is about the same as a soda can, while deep water cables are much thinner—about the size of a Magic Marker. The size difference is related to simple vulnerability—there’s not much going on 8,000 feet below sea level; consequently, there’s less need for galvanized shielding wire. Cables located at shallow depths are buried beneath the ocean floor using high pressure water jets. Though per-mile prices for installation change depending on total length and destination, running a cable across the ocean invariably costs hundreds of millions of dollars.
Sharks are trying to eat the Internet.
There’s disagreement as to why, exactly, sharks like gnawing on submarine communications cables. Maybe it has something to do with electromagnetic fields. Maybe they’re just curious. Maybe they’re trying to disrupt our communications infrastructure before mounting a land-based assault. (Haha) The point remains that sharks are chewing on the Internet, and sometimes damage it. In response, companies such as Google are shielding their cables in shark-proof wire wrappers.
In 1854, installation began on the first transatlantic telegraph cable, which connected Newfoundland and Ireland. Four years later the first transmission was sent, reading: “Laws, Whitehouse received five minutes signal. Coil signals too weak to relay. Try drive slow and regular. I have put intermediate pulley. Reply by coils.” This is, admittedly, not very inspiring. (“Whitehouse” referred to Wildman Whitehouse, the chief electrician of the Atlantic Telegraph Company, who we’ve discussed previously.) For historical context: During those four years of cable construction, Charles Dickens was still writing novels; Walt Whitman published Leaves of Grass; a small settlement called Dallas was formally incorporated in Texas; and Abraham Lincoln, candidate for the U.S. Senate, gave his “House Divided” speech.
As of 2014, there are 285 communications cables at the bottom of the ocean, and 22 of them are not yet in use. These are called “dark cables.” (Once they’re switched on, they’re said to be “lit.”) Submarine cables have a life expectancy of 25 years, during which time they are considered economically viable from a capacity standpoint. Over the last decade, however, global data consumption has exploded. In 2013, Internet traffic was 5 gigabytes per capita; this number is expected to reach 14 gigabytes per capita by 2018. Such an increase would obviously pose a capacity problem and require more frequent cable upgrades. However, new techniques in phase modulation and improvements in submarine line terminal equipment (SLTE) have boosted capacity in some places by as much as 8000%. The wires we have are more than ready for the traffic to come.

This video clip shows a segment of an underwater benthic habitat mapping survey using a Savante Underwater Laser Profiler mounted on a towed sledge vehicle. Sledge-based "ground-truth" habitat mapping surveys are often conducted for reasons of cost and simplicity and at velocities of up to 2knots along the seafloor. Vehicles are often lowered by rope from fishing vessels of opportunity and guided using simple compass, GPS navigational tools and actually very little else.
A real change from the world of 200 million dollar oil and gas construction support vessels and hydroacoustic position referencing systems. Environmental insight into the condition of vast areas of the seabed have been made possible through the economics of this low-cost means of survey.
As demonstrated in this video clip, whilst a towed sledge offers a fantastic viewpoint of the seabed (and the presence of crabs who seem to love our green lasers more than us and often chase the light!!) the presence of boulders and cobbles in the benthic environment often leads to incidents where the entire sledge can topple over. The impulse generated during collisions means that only the hardiest of equipment can be used; no place for a fragile sonar head (often the sensitive rotating head is placed in a soft oil-filled boot) or fibre based technology.
Given the potential for damage to expensive survey tools such as doppler velocity logs and inertial navigation tools (purchase price can exceed 120k GBP as at 2017), we have developed a ruggedised underwater laser profiler to deal with these events. We are able to generate profile data despite these incidents.
A further note of importance - Getting this close to the seabed also enables the volume of water between subject matter and the video cameras to be kept to an absolute minimum (cheers Andy Shiers - veteran ROV pilot). Operating in littoral and estuarine waters can often be subject to high levels of turbidity; close range inspection offers a mobile and realistic approach to acquiring video in these dificult-to-survey areas.

Applications

Aerial mobile mapping

Traditional techniques of geo-referencing aerial photography, ground profiling radar, or Lidar are prohibitively expensive, particularly in inaccessible areas, or where the type of data collected makes interpretation of individual features difficult. Image direct georeferencing, simplifies the mapping control for large scale mapping tasks.

Underwater Mobile Mapping

DOF Subsea, Sonardyne, 2G Robotics, and Seatronics successfully demonstrated a new underwater surveying technique that could significantly shorten the time needed to map underwater structures and offshore sites.
The new technique uses a 3D laser scanner fitted to an ROV to create highly detailed, point cloud images of subsea assets and environments.

Sledge-based "ground-truth" habitat mapping surveys are often conducted for reasons of cost and simplicity and at velocities of up to 2knots along the seafloor. Vehicles are often lowered by rope from fishing vessels of opportunity and guided using simple compass, GPS navigational tools and actually very little else.
A real change from the world of 200 million dollar oil and gas construction support vessels and hydroacoustic position referencing systems. Environmental insight into the condition of vast areas of the seabed have been made possible through the economics of this low-cost means of survey.
As demonstrated in this video clip, whilst a towed sledge offers a fantastic viewpoint of the seabed (and the presence of crabs who seem to love our green lasers more than us and often chase the light!!) the presence of boulders and cobbles in the benthic environment often leads to incidents where the entire sledge can topple over. The impulse generated during collisions means that only the hardiest of equipment can be used; no place for a fragile sonar head (often the sensitive rotating head is placed in a soft oil-filled boot) or fibre based technology.
Given the potential for damage to expensive survey tools such as doppler velocity logs and inertial navigation tools (purchase price can exceed 120k GBP as at 2017), we have developed a ruggedised underwater laser profiler to deal with these events. We are able to generate profile data despite these incidents.
A further note of importance - Getting this close to the seabed also enables the volume of water between subject matter and the video cameras to be kept to an absolute minimum (cheers Andy Shiers - veteran ROV pilot). Operating in littoral and estuarine waters can often be subject to high levels of turbidity; close range inspection offers a mobile and realistic approach to acquiring video in these dificult-to-survey areas.

On July 15th,1942, the German U-boat 576 was sunk off the coast of North Carolina.
Today, you can see an amazing 3D image of U-576 in the form of processed point cloud. This was created using a revolutionary new dynamic underwater mobile scanning technique using lasers.
Using Sonardyne’s LBL acoustic positioning technology, coupled with SPRINTINS, Syrinx Doppler navigation and 2G Robotics’ ULS-500 laser mounted to a manned submersible, NOAA were able to fly over the sunken U-boat whilst simultaneously taking continuous laser scans.

Over 400 submarine cables create an invisible network linking all the continents. Crucial to our connected age, 99% of internet traffic goes through the estimated 1.3 million kilometres of cables. This unnoticed infrastructure is highly important for nation states, intelligence services and internet giants.

Underwater Mobile Mapping

DOF Subsea, Sonardyne, 2G Robotics, and Seatronics successfully demonstrated a new underwater surveying technique that could significantly shorten the time needed to map underwater structures and offshore sites.
The new technique uses a 3D laser scanner fitted to an ROV to create highly detailed, point cloud images of subsea assets and environments. By combining the 3D laser data with precise underwater acoustic and inertial navigation information, it is now possible to generate centimetre resolution engineering models from which accurate measurements can be instantaneously and repeatably captured.

Animated Map of the World's Undersea Internet Cables

http://www.businessinsider.com/animated-map-global-fiber-optic-internet-cables-2015-9 ---- 99% of international data is transmitted by wires at the bottom of the ocean called submarine communications cables. In total, they are hundreds of thousands of miles long and can be as deep as Everest Is tall. The cables are installed by special boats called cable-layers. It’s more than a matter of dropping wires with anvils attached to them—the cables must generally be run across flat surfaces of the ocean floor, and care is taken to avoid coral reefs, sunken ships, fish beds, and other ecological habitats and general obstructions. The diameter of a shallow water cable is about the same as a soda can, while deep water cables are much thinner—about the size of a Magic Marker. The size difference is related to simple vulnerability—there’s not much going on 8,000 feet below sea level; consequently, there’s less need for galvanized shielding wire. Cables located at shallow depths are buried beneath the ocean floor using high pressure water jets. Though per-mile prices for installation change depending on total length and destination, running a cable across the ocean invariably costs hundreds of millions of dollars.
Sharks are trying to eat the Internet.
There’s disagreement as to why, exactly, sharks like gnawing on submarine communications cables. Maybe it has something to do with electromagnetic fields. Maybe they’re just curious. Maybe they’re trying to disrupt our communications infrastructure before mounting a land-based assault. (Haha) The point remains that sharks are chewing on the Internet, and sometimes damage it. In response, companies such as Google are shielding their cables in shark-proof wire wrappers.
In 1854, installation began on the first transatlantic telegraph cable, which connected Newfoundland and Ireland. Four years later the first transmission was sent, reading: “Laws, Whitehouse received five minutes signal. Coil signals too weak to relay. Try drive slow and regular. I have put intermediate pulley. Reply by coils.” This is, admittedly, not very inspiring. (“Whitehouse” referred to Wildman Whitehouse, the chief electrician of the Atlantic Telegraph Company, who we’ve discussed previously.) For historical context: During those four years of cable construction, Charles Dickens was still writing novels; Walt Whitman published Leaves of Grass; a small settlement called Dallas was formally incorporated in Texas; and Abraham Lincoln, candidate for the U.S. Senate, gave his “House Divided” speech.
As of 2014, there are 285 communications cables at the bottom of the ocean, and 22 of them are not yet in use. These are called “dark cables.” (Once they’re switched on, they’re said to be “lit.”) Submarine cables have a life expectancy of 25 years, during which time they are considered economically viable from a capacity standpoint. Over the last decade, however, global data consumption has exploded. In 2013, Internet traffic was 5 gigabytes per capita; this number is expected to reach 14 gigabytes per capita by 2018. Such an increase would obviously pose a capacity problem and require more frequent cable upgrades. However, new techniques in phase modulation and improvements in submarine line terminal equipment (SLTE) have boosted capacity in some places by as much as 8000%. The wires we have are more than ready for the traffic to come.
